Hi,
I appear to have static noise on headphones with the default settings
of the driver
by tinkering with hdaanalyzer i could "kill the noise"
i had to mute Val[2] and Val[3] of the following :
Node 0x0c [Audio Mixer] wcaps 0x20010b: Stereo Amp-In
Amp-In caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
Amp-In vals: [0x00 0x00] [0x00 0x00]
Connection: 2
0x02 0x0b
It seems i can't access these with alsamixer
Could there be a fix ?
Thanks,
Yannick
by the way :
